Reminders of all-day events are not shown correctly under the following conditions:

1. The event is created on another device and synced via CalDAV
2. The reminder time is defined as a relative offset

So e.g. this works fine:

BEGIN:VALARM
ACTION:DISPLAY
TRIGGER;VALUE=DATE-TIME:20171010T190000Z
DESCRIPTION:Default Mozilla Description
END:VALARM

It also works if the event is created on the device itself. But if it is created in e.g. Thunderbird with a relative offset

BEGIN:VALARM
ACTION:DISPLAY
TRIGGER;VALUE=DURATION:-PT12H
DESCRIPTION:Default Mozilla Description
X-KDE-KCALCORE-ENABLED:TRUE
END:VALARM

the alarm is not shown at the correct time (I would expect at noon of the previous day for the example above). Instead the event appears as a "missed reminder" notification some time after midnight (the exact time is difficult to determine for me, as I normally sleep then ;-) But I do see it when I wake up the next morning).

My current software version is SailfishOS 2.1.1.26 on Jolla 1.

Update:

I have now switched my primary usage to Sailfish X, which shows the same behavior.

Looking at /home/nemo/.timed/events.data I see that working alarms have an exact time attached to them:

{ key = "alarmtime", val = "2018-01-06T20:15:00+01:00" },

whereas the non-working ones only have date:

{ key = "APPLICATION", val = "libextendedkcal" },
{ key = "PLUGIN", val = "libCalendarReminder" },
{ key = "TITLE", val = "redacted" },
{ key = "alarmtime", val = "2017-11-16" },
{ key = "endDate", val = "2017-11-16" },

I believe that this is a regression since I faintly remember that this used to work quite some time ago.
